ABSTRACT:
A faucet structure having a hollow housing, a cap threaded with the housing, a valve body encompassed by the housing, and a stem threadedly securing within the valve body. A tubular element integrally and horizontally formed on the upper lateral surface of the housing to receive a water pipe. A steel ball to control the water flow rate is encased in an enlarged bore of the housing with a pad disposed beneath the steel ball to provide a sealing effect. A plurality of vertical strips are formed in the interior of the housing below the enlarged bore, and a threaded hole is laterally disposed through the housing on a pair of the strips which are oriented opposite to each other. A screw is encompassed by each threaded hole and has a tongue horizontally formed on a distal end of the screw to protrude from the surface of the strip and be received by a mortise provided on the valve body. A retaining ring and C-ring are provided on the exterior of the stem to cooperatively define the range that the valve body is threadedly slidable on the stem by turning an irregularly-formed end mounted on the bottom end of the stem.
